如何为 dockerized nodeJS 应用程序设置正确的组成员
How to set correct group member for dockerized nodeJS application
我需要 运行 一个 docker 容器和一个使用 rpio 包的应用程序。
我不明白这部分：
By default the module will use /dev/gpiomem when using simple GPIO access. To access this device, your user will need to be a member of
the gpio group, and you may need to configure udev with the following
rule (as root):
$ cat >/etc/udev/rules.d/20-gpiomem.rules <<EOF
SUBSYSTEM=="bcm2835-gpiomem", KERNEL=="gpiomem", GROUP="gpio",
MODE="0660" EOF
For access to i²c, PWM, and SPI, or if you are running
an older kernel which does not have the bcm2835-gpiomem module, you
will need to run your programs as root for access to /dev/mem.
由于我 运行 在 docker image/container 中安装我的 nodeJS 应用程序，我不明白如何设置组成员以及成员名称和调用位置udev 规则命令。
非常感谢您的每一个解释。
docker 用户（应该是登录用户，例如 "pi"）需要在 "gpio" 组中。
# see all groups the user is assigned to
groups
# if the user is not assigned to gpio, run the following:
sudo adduser $(whoami) gpio
您需要使设备 /dev/gpiomem 在 docker 容器内可用。
# e.g.
docker run -d --device /dev/gpiomem <image>
